Subject: ALSA: usx2y: Use safer strscpy() instead of strcpy()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f3d81c058f4878f31bbf9dcb33b0acc41d02675c;p=thirdparty%2Fkernel%2Flinux.git

ALSA: usx2y: Use safer strscpy() instead of strcpy()

Use a safer function strscpy() instead of strcpy() for copying to
arrays.

Only idiomatic code replacement, and no functional changes.
